FeatureSetCollection {ClassifyR} | R Documentation

## Container for Storing A Collection of Sets

### Description

This container is the required storage format for a collection of sets. Typically, the elements of a set will either be a set of proteins (i.e. character vector) which perform a particular biological process or a set of binary interactions (i.e. Two-column matrix of feature identifiers).

### Constructor

  `FeatureSetCollection(sets)`

`sets`

  A named list. The names of the list describe the sets and the elements of the list specify the features which comprise the sets.

### Summary

A method which summarises the results is available. `featureSets` is a `FeatureSetCollection` object.

  `show(featureSets)`Prints a short summary of what `featureSets` contains.

### Subsetting

The FeatureSetCollection may be subsetted or a single set may be extracted as a vector. `featureSets` is a `FeatureSetCollection` object.

  `featureSets[i:j]`: Reduces the object to a subset of the feature sets between elements `i` and `j` of the collection.

  `featureSets[[i]]`: Extract the feature set identified by `i`. `i` may be a numeric index or the character name of a feature set.
